<P>PROBLEM TO BE SOLVED: To provide a power storage element of a high capacity inexpensively with high reliability, capable of responding to high output usage, by reducing a diffusion time of lithium ions under a horizontal doping method. <P>SOLUTION: This is a power storage element 200 in which a positive electrode 10p is constituted of a material capable of carrying lithium ions or anions reversibly and a negative electrode 10n is constituted of a material capable of storing or releasing lithium ions, and the positive electrode, a separator 30, the negative electrode, and the separator are arranged in order to constitute a set of power generation element 50, and an electrode laminate 100 laminating at least one set or more of the power generation elements is sealed together with an electrolytic solution containing lithium salt. The positive electrode and the negative electrode are made by coating respective active materials of the respective electrodes on the surfaces of current collectors 11p, 11n, respectively, a metal lithium is arranged so as to be in electrical contact with the current collector at least at one place or more in the negative electrode surface, and a through-hole penetrating from the front surface to the rear surface is provided at the current collector of either the positive electrode or the negative electrode. <P>COPYRIGHT: (C)2009,JPO&INPIT |
